Preferably, an internal 'tubular bushin i1 having a flared upper end Il is positioned within the device B and the hose or conduit A at their Junctureso as to reenforce the structure in this region and conilne the expansion to that portion of the device B located between the faucet terminal and the bushing.

What is claimed is: i

1. In a faucet connection, a exible elastic hollow body having a reduced expansible portion providing a restricted throat adapted to grippingly engage'over the end of a faucet and which portion is provided with longitudinally extending, outwardly projecting radially disposed ribs functioning to resiliently maintain the said portion in normally contracted condition and for tensioning the throat for eilecting an'inward contraction of the same about the end of the faucet, and an lenlarged inner end portion merging with the reduced expansible portion, said inner end portion being expansible under pressure of the water owing therethrough which expansion fulcrums the ribs about the faucet end so as to exert a contractile gripping Yaction of the faucet engaging portion with the faucet.

2. In a faucet connection, a flexible elastic hollow body having an expansible portion defining a reduced throat adapted to grippingly engage over the end of -a faucet and an inner portion merging with the faucet engaging portion and which inner portion is expansible under pressure of the water owing therethrough so as to create an enlarged water passage adjacent the inner end of the faucet engaging portion, and means adapted upon the expansion of the inner end portion to exert a contractile gripping taction of `the faucet engaging portion with the auce 3. In a faucet connection. a exlble elastic hollow body including an enlarged outer end portion defining a mouth, a reduced medial portion providing a `restricted expansible throat adapted to engage over the end ofthefaucet, and an inner end portion merging with the medial portion, said reduced medial portion being provided with longitudinally extending outwardly projecting radial ribs having their opposite ends merging respectively with said inner and outer end por'- tions and functioning to inherently maintain said medial portion in normally contracted condition, .said inner end portion being expansible under pressure of the water flowing therethrough to provide an enlarged water passage adjacent the inner end of the faucet engaging portion and said inner end portion being provided with a restricted outlet forming a continuation of the enlarged waterpassage.

4. In a faucet connection, a flexible elastic l hollow body including an enlarged outer end portion defining a mouth, an enlarged expansible inner end portion and a reduced medial portion merging with the said end portions, said medial portion being provided with longitudinally extending outwardly prjecting radial ribs having their opposite ends merging respectively with said inner and outer enlarged end portions and functioning to inherently maintain the said medial portion in normally contracted condition and said inner end portion being expansible under pressure of the water flowing therethrough to spread the inner end portions of the ribs so as to augment the contractile gripping action of the said medial portion.
